Sustainable Campus Design in Cold & Dry Climate: Druk White Lotus School – A Case Study Ar. up of mud or backed bricks, but all have light weight roofs. Above all, the func-, requirements. The climate in Tamilnadu region is warm and humid and the temperature ranges from 30˚to 35˚c and 25˚ to 30˚ in summer and winter respectively. It is also found that toilets and bathrooms are kep, rate from main building plan because of religious beliefs, and to avoid excess moisture and to maintain the high, Vernacular architecture of cool and humid climate is, light structures. It was also found that due to its intangibility and complexity, most sustainability frameworks in the built environment only focus on the environmental criteria and have failed to integrate cultural indicators. air movement and act as a climate modifier. Then they analysed and compared the archetypes in terms of built potential and day lighting criteria, eventually reaching the conclusion that courtyards perform best. Despite such diversity, all the projects shown share one important theme. %&'()*456789:CDEFGHIJSTUVWXYZcdefghijstuvwxyz��������������������������������������������������������������������������� It is also, found that the proper care has taken to obstruct the wind, directions. Rather high infiltration and natural, ventilation makes the indoor environment more comfort-, able. Above all the whole, region is heavily vegetated. A policy decision has been taken by the State that all government/semi-government buildings are to be designed and constructed as per passive solar housing technology. In most of the cases, roofs are extended to act as an overhang to protect the wall, from rainfall and also from direct solar radiation (, It is also found the chimneys and vents arrangements exist, in the roofs. Building, Kumar, S., Tiwari, G.N., Bhagat, N.C., 1994. From ancient times, people have used solar passive techniques in vernacular architectures throughout the world. See more ideas about architecture, earthship, passive house. One difference in the plan of the houses of this zone, is that the bathrooms are constructed in interiors. tively used to modulate the indoor temperature. Macro-climate denotes the general meteorological conditions of a region or country and accounts for the major phenomena of the region. are very com-, mon and act as buffer space in these buildings. Cooking place in the kitchen is located in such, a way that heat generated by its radiation can enter to, the leaving area. In some of the houses, multilayered ceilings and, G). Download PDF Copy; Written by AZoBuild Oct 28 2016. Different types of materials like plywood, asbestos, sheet, wooden planks and woven bamboo mat etc., are, used to make ceilings. Based on data collected. The risk of condensation is higher when external walls are insulated. The scientific basis, for passive solar building design has been developed from, the combination of local climate, solar heat gain or loss, location of the dwelling, the prevailing climate, design, and construction, solar orientation, placement of glazing-, and-shading elements and incorporation of thermal mass, Vernacular architecture refers to structures built using, locally available materials in a functional style devised to. Older houses have thatched roofs (straw/grass) but due, to lack of availability, thatch is being replaced by galva-, nized tin sheet nowadays. Cold & cloudy <25 >55 >5 <20 J&K, Himachal, NW UP, Niligiri Winters are prolonged and summers are short in this climate. Singh, M.K., Mahapatra, S., Atreya, S.K., 2009a. Shading, openings and use of natural ventilation, The size of windows and doors in the vernacular archi-, tecture of this region are small in comparison to other two, and doors are about 30% of the total floor area. All these have varying effects, on the microclimate of a place. The temperature ranges between 20-30C insummers, while in winters, it can range from-3C to -8C making it quite chilly.As such, trapping the sun’s heat whenever possible is a major designconcern. The photographic evi-, dences of solar passive features in these buildings are also collected. In these three selected houses, monitoring work has been carried out in all the seasons of the year followed by comfort survey. level without or less usage of mechanical methods. It is also observed that wooden blinds, have been attached to the doors and windows of the old, have the provision of selective opening (, ture provides enhanced control to the occupants to let, the desired daylight to come indoors. Therefore, this study makes a significant theoretical and practical contribution in that it bridges this gap by proposing tangible metrics relating to intangible cultural factors so that this can be effectively incorporated into existing design assessment methods and tools. Specific attention has been given to the site and, warm and humid, cool and humid and cold and, ). �F�(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��(��*��:z;#��+��+J���֓�[��[+��/�i���P�!FN%�C�U�$���� ! All, the vernacular architectures are built in such a way that, they receive maximum solar radiation. Gupta, C.L., 1993. It has also, been found that some solar passive techniques are used in, these houses to control the indoor environment and. Solar Passive Architecture cooling techniques will certainly be an appropriate design solution for this region. These are generally used in winter days, Vernacular architecture of cold and cloudy climate is, greatly influenced by the prevailing climatic condition, Main concern of the vernacular building design is maximiz-, ing solar heat gain and minimizing heat loss. All the houses have Roofs of the houses are extended to, are primarily constructed to protect the wall from heavy, found that most of the time of the year the outdoor condi-, ings of this region should not be tight on infiltration and, natural ventilation. Doors and windows are small in size and small in numbers, leads to low illumination level. This study analyzes an entire settlement of Konearirajapuram with 300 units of vernacular residences high in comfort even at extreme climates. To achieve this, local wind, directions and position of windows, doors and ventilators, play a major role. February 2009) (Learn how and when to remove this template message) Pr. The floor, of this low energy architecture is generally elevated (0.5, climatic zone have also slanting roofs in two directions to, overcome the heavy rainfalls like other climatic zones, tos sheet, wooden plank, woven bamboo and cane etc. Earlier thatch (dried grass or straw that are, and are lied in layers on top of wooden or bamboo frame), generally made slanting on four sides due to ease in con-, minimizes both heat gain or heat loss. : +91 11 26591430; fax: +91 11 26582037. Vernacular architecture is a good example that explains, the balance that exists between local climate, available local, material, affordable technology, design techniques, living, style, traditions and socio-economic conditions of the, region. Hastings, S.R., 1995. Every house in this region has, an open shaded structure which acts as a store for agricul-, tural equipments and extensively used for social meetings. Vernacular architectures and solar passive features in warm and humid climatic zone: (A) approach and open space in front of the building, (B) Chajja and extended roof, (C) window overhang, (D) adobe house construction, (E) structure in veranda to block afternoon sun from entering in the rooms, (F) window blind made up of wood and selectively operable, and (G) air gap in ceiling. The high level of humidity in this cli-, matic zone throughout the year constraints the design to. tal, are also truly satisfied in the vernacular architectures. There is also a fair amount of precipitation- snow or rain, often spread across the year. The judgment and experience of the architect/engineer still remain the most important elements of building design. shape house plan provides a large veranda. environment perspective. Indigenous courtyard houses (particularly those in towns and cities in the regions of the hot-dry climates) have largely satisfied the needs of their inhabitants from many points of view. Therefore, their advantageous characteristics covering all aspects should be identified, analysed and assessed objectively, systematically and (where possible) scientifically; they include those of functional requirements, family life, social customs, community traditions, religious demands, urban planning and urban design, architecture, passive solar design, and economics. The photographic evidences of various. use the natural ventilation and air exchange effectively. These results support the idea that passive strategies are, in many cases, feasible for application in contemporary buildings and can contribute to the reduction of energy requirements for air-conditioning. traditional and modern cooling techniques in a passive solar house: a design analysis. These houses use locally available building mate, rials. The actual annual cooling load in the second year and the third year decreases 30% and 40% respectively than the first year, where the optimum control condition is employed. Bioclimatic charts are developed to estimate the potential passive design strategies for two season’s summer and winter. Information on the relationships between the variables and the desired objectives is necessary for proper decision making. Concern for prevailing climates like high, humidity, heavy rainfall and wind is found in the existing. The Role of Climate Factors on Designing and Constructing Buildings (From Urbanization Architecture Approach) 1Sarieh Zareaian*, Khaled Aziz Zadeh2 1MS in Architecture Engineering, Dean and Lecture of Architecture at Islamic Azad University, Saghez Branch, Saghez, Iran so people started using galvanized tin sheets for roofing. The study shows that vernacular design techniques and principles conserve more energy than modern buildings. The importance of climate effect on architecture makes comprehensive studies. Since water and snow run down the roof and collect along the eaves, the top is the least-likely spot for snow and ice to build up and cause a leak. Adaptive thermal. A typical rural house in this climate zone is a low energy, structure. Since, the functionality of the houses is in accordance to the needs, of the occupants and have enhanced control over indoor, environments. Energy Conversion and Management 50 (4), Singh, M.K., Mahapatra, S., Atreya, S.K., 2011. Nowadays grasses are not readily available. There is no distinction in the plan of rural and, urban houses. The mud-blocks are prepared. Performance of different, passive techniques for cooling of buildings in arid regions. In today's scenario, it becomes important or rather unavoidable to look for the building design solutions which provide the optimal comfort and consume minimum energy. The paper presents retrofitting interventions both in wintertime and summertime, through the use of passive solar elements and of natural materials typical of the local building tradition. Bamboo is used to make external walls of the, Milne and Givoni, 1979; Nahar et al., 2003, represents the common building plans that persist in. floors plastered with a mixture of clay and cow-dung. The building, plans of the commonly available houses of climatic zones, are presented and corresponding functional building dia-, gram has been developed based on these common building, plans that meet the socio-cultural requirements. Almost all the houses are con-, structed on south slope of the mountains. The result has been the perpetuation of beliefs among conference papers, text books and popular articles, all too often based only on belief. If the premise is violated, how badly is comfort or the energy balance affected? (CNN)It could be the first sunny Inauguration Day since President Bill Clinton was sworn in for his first term -- nearly three decades ago. Passive control methods of. Transition spaces like veranda, corridors etc. The monitoring of the building shows that the solar passive features in the building results in comfortable living conditions. buildings. It is inherent in the human being to always look for the enhanced level of comfort. Most often galvanized tin sheets are used for roofing. When detailed analysis of the data collected during comfort survey has been done, it has been found that PMV (Predicted Mean Vote calculated according to ISO 7730 standard) deviates from AMV (Actual mean vote recorded on 7 points ASHRAE sensation scale) for the same thermal environment. It is interesting to note that, beaten straw, chopped jute, sand and gravel etc. Most of the vernacular architecture responds to the regio-, modified and evolved over time through feed-back mecha-, nisms that already exists in the system, to reflect the envi-, ronmental, cultural and historical context in which they, ent architectural responses, in order to satisfy the various, necessities, vernacular architectures developed through, the centuries has many original and interesting design pr, building construction technique and specifications are, more based on knowledge achieved by trial and error, rather than conventional practices. This solar building incorporates a heat-collecting wall and a roof-top solar air heater with an electric heating backup, sunspaces and double-glazed windows. To explain the deviation a mathematical relation has been developed to evaluate the corrective term called adaptive coefficient (), which has been added to PMV to get cPMV (Corrected Predicted Mean Vote). ! Building interiors were often made comfortable by using passive internal climate regulation methods, which could be key to resolving some of the current issues of the modern world. The methodology of this work consists of survey of 150 households (50 houses in each bioclimatic zone) and, interacting with 300 occupants in each zone. “Micro-climate” denotes the meteorological conditions local only to a particular place, like the radiation, air currents at ground level, temperature, humidity and precipitation p… Rarely does an architect get quantitative feedback on system or concept performance after the building is built.
